Details

Liquid crystals (LCs) were discovered more than a century ago, but their profound impact was in the past four decades through their successful implementation into electronic devices that we are using every day. The research on liquid crystals actively continues in the 21st century and offers unlimited potential in various display or non-display applications. This book covers novel topics related to LCs and is intended for a wide range of researchers in both, academia and industry, from beginners to advanced level professionals in many scientific areas, viz. materials science and engineering, chemistry, physics, optics, photonics, nanotechnology, electrical engineering, and so on.

The book contains topics on nematic and cholesteric LCs, in the form of films or particles, as well as modified LC behavior with variety of dopants, micron and nano-sized particles, microencapsulation of LC particles and modeling of their behavior under an externally applied field. Topics related to the effect on nanomaterials on LC behavior, as well as structural and magnetic properties of different types of iron-containing liquid crystals (metallo-mesogens) are covered, as well. Finally, an overview of different alignment technologies for nematic liquid crystals such as mechanical rubbing of polymer films, obliquely-deposited inorganic films, photo-irradiated, IB-bombarded and patterned surfaces, are briefly reviewed along with several novel alignment concepts. The state of the art in respective fields related to LCs in each chapter is given by leading experts. (Imprint: Nova)

Index

"Cholesteric liquid crystals are historically the first liquid crystalline materials discovered by Friedrich Reinitzer in 1888. Since then, cholesteric liquid crystals are in the focus of scientists and engineers attracting their attention with the peculiar optical and electro-optical properties. Three of the book’s chapters are devoted to different techniques of preparation of microencapsulated polymeric particles and flakes and their electro-optical properties."

"Liquid crystalline materials are an impressive class of condensed mater combining mobility and order, which gives rise to their unique properties and enables outstanding applications usually associated with liquid crystal displays that can be found in TV screens, computer monitors, tablets, mobile phones, but also in more advanced applications in photonics, telecommunications, medicine and other fields."
